James Duong commented on ARROW-10206:
-------------------------------------
In the PR above, we support building against multiple versions of gRPC.
1. Prior to 1.27, the features in gRPC needed to support this don't exist. The
option to disable server verification fails at runtime if used.
2. Between 1.27 to 1.31 (inclusive), the features needed are in the
grpc_impl::experimental namespace. Compile the code in Flight client using that
namespace.
3. From 1.32 and later, the features are in the grpc::experimental namespace.
Compile the code in Flight client using that namespace.

> Note that this requires using grpc-cpp version 1.25 or higher.
> This requires using GRPC's TlsCredentials class, which is in a different
> namespace for 1.25-1.31 vs. 1.32+ as well.
> This class and its related options provide an option to disable server
> certificate checks and require the caller to supply a callback to be used
> instead.
